@kirimin How's your progress on this~? Is there something we can help you with? 🕵️‍♀️

[kirimin]

@panpanini I'm so sorry for this. 🙏 I don't begin this task yet because of my business work and personal illness... I think I should release this task to other contributors for don't late to the conference. 😢

[panpanini]

Oh that's unfortunate... I hope you feel better soon! I'll unassign you for now then

Can I try this ? 🙋

[takahirom]

Thank you for challenging this issue!

Should Worker show any notification to indicate working as same as IntentService? I guess notifications are used to start foreground service and these will not be necessary.

[jmatsu]

@geckour Good question. No need to keep the current notifications because those notifications were shown due to foreground service matter but not by design.

[geckour]

@jmatsu Thanks, I got it!

[geckour]

I have one more question... If Worker uses Exponential Backoff, does it still needs limitation of retry times (currently set max to 3)?

[jmatsu]

I guess that's also needless. The previous 3 was just an experimental value. 👍

@jmatsu Thanks!
